Indic typing booster Indic typing booster is a predictive input method for the ibus platform. It suggests complete words based on partial input, and users can simply select a word from the suggestion list and improve their typing speed and accuracy. Thanks to the development led by Pravin Satpute and Naveen Kumar, Red Hat I18N team engineers in Pune, India.

Better crash reporting ABRT, a crash reporting tool in Fedora, can now perform a part of crash processing remotely, on a Fedora Project server. Remote coredump retracing avoids users having to download a large amount of debug information and leads to better quality reports. The retrace server can generate good backtraces with a much higher success rate than local retracing.

Redesigned SELinux troubleshooter SELinux troubleshooter is a graphical tool that watches and analyses log files and automatically provides solutions to common issues. In this release, this tool has been redesigned to be simpler but provide more solutions at the same time. Thanks to Dan Walsh, SELinux developer at Red Hat, for leading the development of this functionality.

Higher compression in live images Live images in this release use XZ compression instead of gzip as in older releases, making them smaller (about 10%) to download or providing more space for applications to be made available by default. Thanks to Bruno Wolff III, Fedora community volunteer, for integrating this functionality in Fedora Live CD tools. Thanks to Phillip Lougher for his work on squashfs and Lasse Collin for getting XZ squashfs support in the upstream Linux kernel.

Better power management Fedora 15 includes a redesigned and better version of powertop and newer versions of tuned and pm-utils for better power management. The tuned package contains a daemon that tunes system settings dynamically to balance between power consumption and performance. It also performs various kernel tunings according to selected profile. The new version of tuned brings several bug fixes, improvements and profiles updates for better efficiency. Thanks to Jaroslav Škarvada, Red Hat developer, for integrating the newer powertop and pm-utils, as well as performing power measurement and benchmarking. Thanks to Jan Včelák, Red Hat developer, for developing tuned and integrating the newer version in this release.

LibreOffice productivity suite LibreOffice is a community-driven and developed free and open source personal productivity suite which is a project of the not-for-profit organization, The Document Foundation. It is a fork of OpenOffice.org with a diverse community of contributors including developers from Red Hat, Novell and many volunteers. OpenOffice.org has been replaced with LibreOffice in this release. Thanks to Caolán McNamara from Red Hat for his upstream participation and for maintaining LibreOffice in Fedora.

Firefox 4 web browser A new major version of this popular browser from the Mozilla non-profit foundation is part of this release. Firefox 4 features JavaScript execution speeds up to six times faster than the previous version, new capabilities such as Firefox Sync, native support for the patent unencumbered WebM multimedia format, HTML5 technologies and a completely revised user interface. Thanks to Christopher Aillon from Red Hat and others for integrating Firefox 4 in this release.

KDE plasma workspaces 4.6 and Xfce 4.8 desktop environments Fedora 15 includes new major versions of these alternative desktop environments. Fedora also provides dedicated KDE Plasma Workspaces and Xfce installable live images that include these desktop environments by default. Thanks to Red Hat developers and other Fedora community volunteers, part of KDE and Xfce special interest groups.

Sugar .92 learning platform Sugar is a desktop environment originally designed for the OLPC project which has now evolved into a learning platform developed by the non-profit Sugar Labs foundation. This version provides major usability improvements for the first login screen and the control panel, as well as new features such as support for 3G networks. Thanks to Peter Robinson and Sebastian Dziallas, Fedora community volunteers, for leading the integration of this environment.

BoxGrinder appliance creator BoxGrinder is a set of free and open source tools used for building appliances (images/virtual machines) for various platforms (KVM, Xen, VMware, EC2). BoxGrinder creates appliances from simple plain text appliance definition files. Thanks to Marek Goldmann and others from Red Hat for upstream participation and bringing this feature into Fedora.

Spice integration in Virt Manager With Fedora 15, virt-manager has been updated to support Spice, the complete open source solution for interaction with virtualized desktops. It is now possible to create a virtual machine with Spice support without touching the command line, easily taking advantage of all the Spice enhancements directly from virt-manager. Spice provides better performance and additional functionality (such as copy/paste between guest and host) compared to using VNC. Thanks to the spice-gtk library, a new client can be developed in Python or C, or with gobject-introspection bindings. Thanks to Marc-André Lureau, Red Hat developer, for leading development of this feature.

Consistent network device naming Servers often have multiple Ethernet ports, either embedded on the motherboard, or on add-in PCI cards. Linux has traditionally named these ports ethX, but there has been no correlation of the ethX names to the chassis labels - the ethX names are non-deterministic. Starting in Fedora 15, Ethernet ports will have a new naming scheme corresponding to physical locations, rather than ethX. By changing the naming convention, system administrators will no longer have to guess at the ethX to physical port mapping, or invoke workarounds on each system to rename them into some "sane" order. This feature is enabled on all physical systems that expose network port naming information in SMBIOS 2.6 or later. Thanks to Jordan Hargrave, Matt Domsch and several other engineers from Dell for their long term upstream participation and collaboration with Fedora in integration of this feature.

Setuid removal Fedora 15 removes setuid in several applications and instead specifically assigns the capabilities required by each application to improve security by reducing the impact of any potential vulnerabilities in these applications. Thanks to Daniel Walsh from Red Hat for leading the integration of this feature.

Improved support for encrypted home directory Fedora 15 brings in improved support for eCryptfs, a stacked cryptographic filesystem for Linux. Starting from Fedora 15, authconfig can be used to automatically mount a private encrypted part of the home directory when a user logs in. Thanks to Paolo Bonzini from Red Hat for integration of this feature.

RPM 4.9.0 package manager RPM 4.9.0 brings a number of immediate benefits to Fedora including the pluggable dependency generator, built-in filtering of generated dependencies, additional package ordering hinting mechanism, performance improvements and many bugfixes. More details at https://rpm.org/wiki/Releases/4.9.0, Thanks to Panu Matilainen from Red Hat and other RPM developers for their participation and help in integration of this feature in this release.

Tryton ERP system Tryton is a three-tier general-purpose application platform and basis for an ERP (Enterprise Resource Planning) system. Currently, the main modules available for Tryton cover accounting, invoicing, sale management, purchase management, analytic accounting and inventory management Thanks to Dan Horák, Fedora community volunteer for integration of this feature.

And that's only the beginning. A more complete list with details of all the new features on board Fedora 15 is available at:

Looking forward to Fedora 16 (Verne)

Our next release, Fedora 16 codename is named after and to honor, Jules Verne. Jules Verne is considered a father of science-fiction. He was a science-fiction writer and futurist, best known for novels such as "Twenty Thousand Leagues Under the Sea". More information at

Even as we continue to provide updates with enhancements and bug fixes to improve the Fedora 15 experience, our next release, Fedora 16, is already being developed in parallel, and has been open for active development for several months already. We have an early schedule for an end of Oct 2011 release:

Features planned for Fedora 16 include the default use of Btrfs as the next generation filesystem, GRUB 2 bootloader by default, further enhancements to systemd system and session manager, dynamic firewall by default and much much more. Watch the feature list page for updates.
